Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.124 kg/s, and it leaves at 0.7 mpa and 50°c. the refrigerant is cooled in the condenser to 24°c and 0.65 mpa, and it is throttled to 0.15 mpa. disregarding any heat transfer and pressure drops in the connecting lines between the components, determine (a) the rate of heat removal from the refrigerated space and the power input to the compressor ql kw (round to one decimal place) kw (round to two decimal places) win = (b) the isentropic efficiency of the compressor, % (round to one decimal place) ис and (c) the cop of the refrigerator соpr (round to two decimal places)
